Razor

Hi,

I have the following razor macro which is nearly working but I can't work out why it outputs "if(countItem==1) </div>" to the page. Any help would be great as I've been staring at this for ages now and making no progress:-

@inherits umbraco.MacroEngines.DynamicNodeContext

@{     
    int level = 2;
    var subjects = @Model.AncestorOrSelf(level).Children.Where("nodeTypeAlias == \"SideGallerySectionHeading\"");
    int countItem = 1;

    if (subjects != null) {
      <div class="highslide-gallery">
          @foreach(var subjectName in subjects){
          <h3>@subjectName.Name</h3>           
          foreach(dynamic image in subjectName.Children) {
              if(countItem==1){<div class="picrowdiv">}
              <div class="picdiv">
                  <a href="@image.Media("itemLarge","umbracoFile")" class="highslide" onclick="return hs.expand(this)">
                  <img src="@image.Media("itemThumbnail","umbracoFile")" width="100" height="100" alt="test"></a>
                  <div class="highslide-caption">
                    @image.bodyText
                  </div>
                  <p>@image.caption</p>
              </div>
              if(countItem==1){</div>}
              countItem++;                                                
              if(countItem>2){countItem=1;}
            }
          }
      </div>
    }
}

Hi. Try to replace
```
foreach(dynamic image in subjectName.Children) {
```
with
```
@foreach(dynamic image in subjectName.Children) {
```

That gives:-

Error occured

Unexpected "foreach" keyword after "@" character. Once inside code, you do not need to prefix constructs like "foreach" with "@".

Looks like the Razor parses is not distinguishing correctly between the markup and code, this is possibly because you don't close the div inside the if statement. Try changing to something like this (not tested)

@inherits umbraco.MacroEngines.DynamicNodeContext

@{     
    int level =2;
    var subjects =@Model.AncestorOrSelf(level).Children.Where("nodeTypeAlias == \"SideGallerySectionHeading\"");
    int countItem =1;
  
    if(subjects !=null){
      <div class="highslide-gallery">
          @foreach(var subjectName in subjects){
          <h3>@subjectName.Name</h3>           
          foreach(dynamic image in subjectName.Children) {
              if(countItem==1) {
 @:<div class="picrowdiv">
 }
              <div class="picdiv">
                  <a href="@image.Media("itemLarge","umbracoFile")" class="highslide" onclick="return hs.expand(this)">
                  <img src="@image.Media("itemThumbnail","umbracoFile")" width="100" height="100" alt="test"></a>
                  <div class="highslide-caption">
                    @image.bodyText
                  </div>
                  <p>@image.caption</p>
              </div>
              if(countItem==1) {
 @:</div>
 }
              countItem++;                                                
              if(countItem>2){countItem=1;}
            }
          }
      </div>
    }
}
